Report of the Determination of the Components of the Reverse Current Flowing in the Control Grid Circuit of Negatively Biased Transmitting Tubes
Abstract
The performance of a vacuum tube and, in general, its state or condition at any one time, may be indicated by the negative or reverse current flowing in the control grid circuit when this grid is at a negative potential with respect to the cathode. This is of particular importance with transmitting tubes since the amount of reverse grid current, an important component of which is due to gas, is also an indication of the life expectancy of such tubes. The importance of these facts has been recognized by the Bureau and a problem was assigned to the Laboratory for investigation and study. This report is intended to give the results of this investigation.
